Retrieves the sum of the cycle time of all threads of the specified process
#include <WinAPISys.au3>
_WinAPI_QueryProcessCycleTime( $iPid = 0 )
| $iPid | Pid of the process (Default = @AutoItPID) |
| Success: | The cycle time of the specified process. |
| Failure: | Sets the @error flag to non-zero, call _WinAPI_GetLastError() to get extended error information. |
